Dam Engineering: Types, Components, and Control Mechanisms
DAMS
Definition
Dams are water reservoirs designed to store water. Their primary functions include:
- Supplying water for consumption
- Controlling water flow to prevent flooding
- Harnessing water power and transforming it into other forms of energy (electrical, mechanical, etc.)
Classification of Dams
Types of Dams Based on Structure:
- Gravity Dams
- Lightweight Gravity Dams (Buttress Dams)
- Arch Dams
Types of Dams Based on Material:
- Concrete Dams
- Embankment Dams
- Composite Dams
Types of Dams Based on Application:
- Check

The Water Cycle, Pollution & Sustainability of Aquatic Resources
The Water Cycle
- Renewable: atmosphere, rivers (circular process)
- Middle ground: groundwater aquifers
- Non-renewable: oceans, icecaps
Transfers are: advection, flooding, surface run-off.
Storages: oceans, soils, groundwater, lakes
Human Impact on the Water Cycle
- Withdrawals: domestic use, irrigation in agriculture and industry
- Discharges: adding pollutants to water
- Diverting rivers or sections of rivers
Urbanization and Flash Floods
Ocean Currents and Energy Distribution
- Ocean currents: movements of water vertically
Natural Hazards and Risk Assessment
Natural Hazards and Risk
Natural hazard is defined as the probability, small or large, that the population of an area suffers damage or disaster resulting from a natural process. Risk is the probability of losing human lives, property, or productive capacity due to any natural phenomenon. Natural hazards are physical phenomena of geological, atmospheric, or hydrologic origin that occur slowly or quickly and affect a territory or area at national, regional, or global levels. Geohazards can be endogenous

Planetary System
A planetary system consists of one or several central stars and planets orbiting around them.
- Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
- Dwarf Planets: Pluto, Eris, Ceres, Makemake, Orcus, Sedna…
Celestial Motion
- Planets revolve around stars.
- Satellites revolve around planets.
- Comets revolve around the Sun. A comet is a ball of gas and dust with a tail.
- Asteroids orbit within a star system. When entering a planet’s atmosphere, they disintegrate and fall as
